I have an ASUS P5W64 WS Prof Motherboard with 2 x BFG 7600GT graphics cards in it. The cards are in slot 16_1 & 16_2 on the MB. I now have 3 Viewsonic 924 19" Monitors (the 3rd one arrived today) but I am having real trouble getting this third monitor up and running. The intention is to get the desktop to extend across all three monitors. Display Settings recognises the three monitors (the three LCD icons appear) but as yet I have been unable to get anything to show on it! Am I missing a trick here? Any help would be very much appreciated. Kind regards, Alexis.
